When installing your pneumatic ball valve into the pipeline, proper gasket and seal selection are crucial to prevent leaks. Use materials compatible with your media and pressure, such as PTFE or rubber gaskets for most applications. Make sure the gasket sits evenly between the flange faces or threaded connections.

Follow the bolt tightening sequence carefully—always use a star or cross pattern to ensure even pressure on the gasket. This prevents warping and ensures a tight seal.

Bolt Tightening Sequence:

• Tighten bolts in a crisscross/star pattern
• Start with a light torque, then gradually increase in stages
• Avoid fully tightening one bolt before moving to the next

Torque Specifications (based on valve size):

Valve Size (inches)	Bolt Torque (ft-lbs)
1/2″ – 1″	15 – 20
1-1/4″ – 2″	25 – 30
2-1/2″ – 4″	35 – 45

Be sure to check your valve’s technical specs for precise torque values, especially for DELCO pneumatic ball valves. Proper torque helps avoid leaks and maintains the valve’s integrity during operation.

For more detailed bolt torque information and to ensure proper valve fit, check out DELCO’s pneumatic actuator and valve mounting guidelines available on their website. This helps ensure you’re aligning the actuator correctly when the valve is fully installed.

Connecting the Compressed Air Supply

Properly connecting the compressed air supply is crucial for pneumatic ball valve operation. Here’s what you need to know:

• Tubing Size & Material: Use tubing that matches the actuator’s inlet size—typically 1/4” or 3/8” OD is common. Materials like polyurethane or nylon offer flexibility and durability, while copper or stainless steel tubing works best in high-temp or corrosive environments.
• Fitting Types: Push-to-connect fittings simplify installation and maintenance, perfect for quick connections without tools. NPT threaded fittings provide secure, leak-proof joints but require thread sealant and proper torque.
• Air Filter, Regulator, Lubricator (FRL): Always install an FRL unit upstream. It cleans moisture and particles, regulates pressure, and lubricates the actuator to extend its life. This step avoids premature wear and keeps performance steady.
• Supply Pressure Range: For DELCO pneumatic actuators, maintain a supply pressure between 60 to 100 PSI. Never exceed the maximum pressure rating to prevent damage or unsafe conditions.

Following these tips ensures reliable valve action and longer service life for your pneumatic actuated ball valve.

Wiring the Solenoid Valve (if applicable)

If your pneumatic ball valve comes with a solenoid valve, proper wiring is crucial for safe and reliable operation. Most solenoids support common voltages like 24V DC, 110V AC, and 220V AC, so first confirm the voltage rating on your unit before wiring.

NAMUR Solenoid Mounting

DELCO solenoid valves are often designed for NAMUR mounting, which means the solenoid snaps right onto the actuator with standardized fittings, making installation straightforward. Just ensure the solenoid is aligned properly for the best connection and avoid forcing parts to prevent damage.

Simple Wiring Tips

• Use wire gauge suited to your solenoid voltage and current specs—typically 18-22 AWG for low voltage DC.
• Route wires away from sharp edges and heat sources.
• Connect the positive and negative leads correctly; reversing polarity can damage some solenoids.
• Ground the system properly if your model requires it.

Here’s a basic wiring overview:

Voltage	Wiring Notes
24V DC	Polarity sensitive; use DC-rated cables
110V AC	Polarity usually not critical; use rated AC wiring
220V AC	Ensure correct phase and neutral; follow local electrical codes

Safety Notes

• Always turn off power and disconnect compressed air before wiring.
• Follow local electrical codes and use proper PPE.
• Double-check all connections before powering up.
• If unsure, hire a qualified electrician.

Proper wiring of the solenoid valve controls your pneumatic ball valve’s open/close function efficiently and ensures long-term reliability without unexpected failures. For an example of integrated pneumatic ball valve designs with solenoids, check DELCO’s pneumatic jacketed ball valve series.

Setting Stroke and Limit Switches

Once your pneumatic ball valve and actuator are securely installed, the next step is setting the stroke and adjusting the limit switches to ensure precise open and closed positions.

Manual Override Procedure

Most pneumatic actuators include a manual override, allowing you to operate the valve by hand during setup or emergencies:

• Locate the manual override knob or lever on the actuator.
• Engage the manual control to turn the valve between fully open (90°) and fully closed (0°) positions.
• This helps verify the valve mechanically responds before applying air pressure.

Adjusting Stroke from 0° to 90°

Proper stroke adjustment guarantees the ball valve fully opens and shuts without strain:

• Access the actuator’s stroke adjustment screws or cams, usually located near the linkage.
• Using the manual override, slowly move the valve to the open position.
• Adjust the “open” limit switch so the actuator stops precisely at 90°, ensuring a tight seal.
• Repeat the process for the closed position, setting the “closed” limit switch to 0°, confirming the valve fully seats.
• Keep in mind DELCO actuators offer clear settings for double acting or spring-return configurations to match your valve’s operation.

Fine-Tuning Open/Closed Positions

Fine-tuning eliminates leaks and wear caused by misalignment:

• Test valve operation under compressed air supply.
• Observe if the valve fully opens and closes with no unusual noise or resistance.
• Slightly adjust the limit switches if you spot any drift or incomplete strokes.
• Once confirmed, tighten all adjustment screws securely.

Correct stroke and limit switch setup maximize valve life and performance, helping you avoid common issues like incomplete sealing or actuator overtravel.

Testing & Commissioning

After installing your pneumatic ball valve, thorough testing and commissioning are essential to ensure everything works smoothly and safely.

Dry Cycle Test (No Media)

Start by operating the valve through several open and close cycles without any fluid or gas in the pipeline. This helps verify that the pneumatic actuator and ball valve move freely without sticking or unusual noises. Check the actuator response time and listen for any air leaks.

Pressure Leak Test Procedure

With the valve installed, pressurize the pipeline at working pressure. Inspect the valve body, seals, flanges, and connections for any signs of leakage. Use a soap solution or leak detector spray around joints and seals for easy visual detection of leaks. Tighten bolts following the recommended torque settings if necessary.

Full Stroke Test With Media

Once leak-free, start flow through the valve and cycle it fully open and fully closed under normal operating conditions. Watch for smooth operation and confirm that the valve seats properly without flow or pressure drop issues.

Verifying Fail-Safe Function

For spring-return actuators (single-acting), simulate air supply failure to confirm the valve returns automatically to its safe position (open or closed). This is critical for system safety and compliance. Check that limit switches and position indicators correspond correctly to valve status.

Following these test steps ensures your pneumatic actuated ball valve installation is reliable, leak-free, and ready for safe operation. Regular testing during commissioning can catch early issues before full-scale use.
